Charles Denike projects cool and calm, and carries the air of someone who can handle business if things start to go sideways. There’s also a sense that he’s not one to be fazed by someone else’s nonsense.

Denike, then, is an ideal NASCAR crew chief. For some, he’s only now becoming more of a household name – or at least more familiar – in that role for Bubba Wallace as 23XI Racing.

But he was winning races while flying under the radar over the last five years in the Craftsman Truck Series at McAnally-Hilgemann Racing. Most recently, Denike guided Christian Eckes to eight wins between 2022 and 2023, and back-to-back top-five finishes in the championship standings.

On Sunday at Darlington Raceway, the Virginia native’s straightforwardness could be heard on the No. 23 radio. In the second stage, Wallace had a stint where he went from running inside the top five to eighth place. There was a radio communication during which Wallace appeared to say everything was fine.

Denike, on the channel heard by the spotter and not the driver, disagreed. His response was, “We’re not fine if we’re bleeding five spots. So, we’re going to keep pushing.”

His background might have something to do with such personality traits.

“I went into the military after college,” Denike said.

There is no one answer as to why Denike chose that route. On one hand, he says, he saw it as an opportunity to travel. But also, his father served in Vietnam, which Denike found to be a natural inspiration.

An engineer officer in the U.S. Army, some of what Denike did was underwater search and salvage, and later in his career, work in logistics. He served in Haiti after a devastating earthquake and in Afghanistan, earning a Bronze Star during the latter.
